Abstract

The invention relates to the field of power transformers, in particular to a transformer iron core structure and a power transformer. The transformer iron core structure comprises a shell, a bottom plate cavity, a slotted support frame, a transformation component and the like; and a bottom plate cavity is fixedly installed in the shell, a slotting supporting frame is fixedly installed on the bottom plate cavity, and the voltage transformation component is arranged on the slotting supporting frame. By arranging the silicon steel binding posts, the silicon steel binding posts utilize orientation of silicon steel sheets and an annealing process, additional loss can be reduced, current transmission efficiency can be improved, the silicon steel iron chips are made of high-permeability silicon steel sheets, loss is fully reduced, meanwhile, the silicon steel iron chips are stacked in a stepped mode, iron loss can be reduced by about 8%, and the purpose of effectively reducing loss is achieved.

Description

technical field [0001] The invention relates to the field of power transformers, in particular to a transformer core structure and a power transformer. Background technique [0002] With the rapid development of the entire national economy, the demand for transformers will continue to increase. Power transformers are one of the most important equipment in the power system and the basis for ensuring the reliability of power supply. Composed of two or more coil windings, the windings are connected by an alternating magnetic field and work according to the principle of electromagnetic induction. The installation location of the transformer should be considered to be convenient for operation, maintenance and transportation, and a safe and reliable place should be selected. [0003] The rated capacity of the transformer should be selected according to the needs of the power load. The traditional transformer cannot control the capacity of the transformer according to the power loa...
